<p>Each cell (1, 1' and 1 n) of an accumulator (3) is provided with a peripheral electronic control unit (CCU, 4) which is connected to sensors of temperature, voltage and/or other operating parameters of each individual cell and/or is connected to means for controlling the charging or discharging phase of the cell, and this peripheral control unit is designed to be connected to a small data reception and transmission (Rx/Tx) unit (6), operating for example at radio frequency or by means of another wireless system. The accumulator is provided with at least one central electronic control unit (BMS, 8) which can be connected by means of a CPU (9) and its own Rx/Tx unit (7) to the corresponding Rx/Tx units (6) of the individual cells in order to receive from these the data on the operation of the cells, for the purpose of comparing these with programmed safety data and automatically interrupting the operation of the accumulator if the operating data obtained from one or more cells differ from preset and programmed values, and/or for the purpose of transmitting regulating and balancing commands to the cells in order to prolong the correct and safe operation of the electric accumulator (3).</p> |
